The casting nozzle is made of high-purity first-grade electrolytic copper plate as raw material, which is melted in an induction furnace and cast in a sand core. In our country, cast nozzles are widely used and are a promising nozzle.

Advantages of cast nozzles:

(1) The cast nozzle is not restricted by machining conditions, and any complex shape can be formed by casting, so the structure is reasonable and the oxygen lance has a long life.

(2) The casting nozzle can be arranged with a hole pattern according to the requirements of the smelting process, and the cooling water channel can also be arranged according to the requirements of water cooling. Therefore, the structure of the casting nozzle is reasonable.

(3) The production cost is relatively low and the product price is cost-effective.
